No one ever replied to that?
Max combined engine timing should be 33 to 34 degrees.
Initial distributor timing should be set per the owner's manual when
using a stock cam and your timing chain is not streched. As your timing
chain wears (streches) the timing will need to be set a little more
advanced to make up for the change in crank to cam timing.
Hotter cams will require a more advanced initial timing (so the advance
needs to be less to make 34 degrees total advance)
The advance should not start kicking in until a couple hundred RPM above
idle. If it kicks in too early (at idle RPM) your idle speed will vary
with a number of factors because the advance affects the idle RPM, which
affects the advance & so on.
